To all whom} it may concern:

Be it known that-I, HENRY A. ROWLAND, a citizen of the United States, residing at Bal-v timore city, in the State of Maryland, have invented certain new and useful Improvements in Page-Printing Machines, (Case E;)

and I'do hereby declare the following to be a full, clear, and exact description of the inventiorr, such as will enable others skilled in the art to which it appertains to make and use the same. i

My present invention relates to improver ments in page-printers, and more particularly to an improved form of printing-machine by which telegraphic signals may be translated into typographical characters and printed in page form upon sheets of paper.

In carrying out my said invention the paper upon which the characters are printed is delivered to the printer-carriage either from a roll, in single sheets, or in any other convenient manner. The printer-carriage, actu ated by suitable spacing mechanism,'moves the paper step by step under a continuouslyrotating type-wheel until-the end of a line is reached, when by the operation of a proper lining mechanism the pap'er is fed up, a new line is formed, and the-carriage is returned to its original position, though the carriage may be caused to reverse its motion or return to its original position at any desired poin t' in its travel. The characters are printed by an electricallyoperated platen, which is caused to strike the paper and bring it in con tact with the proper character on the typewheel for each combination of signals received. In order to accomplish this, as well as to actuate the spacer, liner, and other electrical devices of the 'printer,'l employ as a part of my present invention circuit-combining devices constituting an improvement upon somewhat similar devices shown and described in my United States patent application for multiplex printing-telegraphs, filed July 26, 1897, Serial No. 646,017.

Owing to the-weight of the printer-carriages V and paper-carrying devices hitherto used in printerso f this general character some difficulty has been encountered in getting these devices to move fast enough, being usually tuating device in side elevation.

Fig. 3 is a top plan view of the printer shown in the preceding views having the paper removed, but showing the printer-relays in position.

Fig. 11 is a detail view, in frontelevation, of the releasing-gearing employed to return the carriage to its initial position, the same being shown with its cover-plate removed. Fig. 12 is a diagram showing the various electrical connections of the printer and its actuating-relays and combination devices. Fig. 13 is a diagram illustrating the action of the circuit-combining apparatus. Fig. 14 represents a portion of the printer in side elevation, showing a somewhat difierent method of returning the carriage to the beginning of a new line. Fig. 15 represents a section taken along the line 15 15, Fig. 16; and Fig. 16 represents an end elevation of the magnetic clutch mechanism for returning the carriage.

Aillustrates the frame of the printer, having a front portion A and rear portion A the former being shown as detachably secured to the latter, but may be cast integral therewithiffound nioreconvenient. Thefrontportion A'is provided with the upwardly-extending brackets a, to the upper faces of which is secured the plate B. Just in the rear of the brackets a are the uprights Ct, which are secured to the front portion of the frame of the machine and carry the rollers a". (Shown most clearly in Figs. 2, 3, and 4.) Each of the rollers a has an annular groove around its periphery, in which rests the rod 0, which carries the printer-carriage D. This carriage consists, among other parts, of a light metal bar 61, preferably of aluminium, and near the center of this bar are two vertical hangers d, engaging at their upper ends the rod 0. At or near each end of the bar (1 are secured the curved uprights d carrying at their upper ends the screw-threaded studs d Secured to each of these studs (1 is a rod d the ends of which are held between the nuts (1 on said studs. About midway between the ends of this rod (1* is a roller d mounted fast thereon and adapted to engage a roughened roller d mounted fast on the shaft 0 and between the hangers d. Curved uprights d are secured to said carriage-bar d and extend below the same, engaging the guide-bar a and preventingthe carriagefrom slippingoutofits course, the upwardly-extending curved portions acting as guides or deflectors for the paper.

The paper E, upon which the characters are printed, is carried by the carriage in the following manner: The carriage is provided with a guideframe consisting of two depending rods d secured at their upper ends to the carriage-bar d and having their lower ends joined by the horizontal member d which latter is provided with two adjustable paper-guides d. The edges of the paper pass through the guides d, while the center of the sheet is held between the rollers d and (1 The paper-guides d consist each of a metal plate bent back upon itself, forming two lips between which the paper is held, as shown most clearly in Fig. 7, and provided with the lugs d, which engage the lower member {Z of the guide-frame and are held fast thereto by the set-screws d. It has been found that by thus supporting the sheet ata central point, as between the rollers d and (Z and providing the side guides d below a much more perfect alinement of the printed characters may be had than by the ordinary way of employing two cylinders that extend across the sheet or employing two sets of rollers at the edges of the paper. The paper thus held upon the carriage passes beneath the type-wheel F, which is mounted upon the shaft G, journaled in the uprights G G The shaft G is driven at a constant speed and regulated, preferably, by the synchronizing mechanism described in my Patent No. 622,636, granted April 4, 1899, or such as is described either in mypatent application, Serial No. 6i6,0l7, filed July 26, 1897, or in my patent application, Serial No. 706,729, filed February 24, 1899, all improvements in multiplex telegraph systems. The shaft G may be connected to the driving power in any suitable manner, a very good way being to have an arm G secured fast to the shaft G, which may be engaged by an arm or lug on a driving-shaft. (Not shown.)

In order to prevent blurring of the characte'rs, as well as to prevent the spced'of the shaft G from being disturbed bythe blows of the platen, the type-wheel provided with the sleevefis loosely mounted upon the shaft G and driven from a disk f, mounted fast on the said shaft near the type-wheel. This disk is provided with a plurality of apertures f through one of which passes a screw f and engages a lug f on the type-Wheel. (See Figs. 1, 9, and 10.) A coil-spring f is secured atits outer end to the type-wheel as at] and at its inner end to a lug f, fast on the shaft G, so that when the type-wheel is struck by the platen it may momentarily pause in order to allow a clear impression of the type to be made upon the paper, when it is quickly brought up to its proper position by the said spring. The tension of this spring is varied by placing the screwf in the different holesf".

H indicates an ink-roller resting upon the periphery of the type-wheel and rotatably mounted in the arms h of the fork h. The fork h is provided with lugs 11 which are carried in the vertical slots 72 of the supporting-bracket h, secured to the upright G, and is also provided with a rearwardly-extending rod or handle it, by which, together with the ink-roller, it may be lifted from the bracket when desired. In order to prevent the paper in proximity to the type-wheel from being deranged or flying up, a spring retaining-strip b is secured, as at b, to the plate B and provided with adjusting-screws b. The strip 1) is bifurcated, as at N, the bifurcation passing on each side of the type-wheel, as shown. The tension of this part of the strip against the paper is regulated by the screw (2 carried in a bracket 19 secured to the upright G.

K indicates the platen pivotally supported, as at 70, in a frame 7a, which latter is secured to the front frame portion A. (See Fig. 9.)

The platen is provided with the depending metallic arm which is located near-the pole of an electromagnet 76', secured to the same result.

frame it". This depending arm 10 is provided with the contact-spring k ,,which when the magnet attracts the'arm 10 will make contact with the contact-screw 16 which completes an electric circuit, hereinafter described, the screw 70 being insulated from the frame of the machine. The throw of the arm 10 is limited by the screw it. It will thus be seen that the action of the printer'magnet k is twofold. vAt each time that it is excited it attracts the arm 10 and causes the platen to strike the paper and print a character and at the same time completes an electric circuit through the contact 70 By closing this circuit at 10 several things are accomplished.

It actuates a relay that breaks the circuit through the printer-magnet and causes the platen to return to its initial position, while atthe same time actuating other relay-magnets which cause the paper to space up and the tongue of the carriage-returning relay or back relay to'be carried back, all of which will be fully described hereinafter in the description of the operation of the machine.

Motion is imparted to the carriage D, by which the paper is caused to travel beneath the type-wheel in a transverse direction, in

the following way: A cord or chain L is secured at one end to a pin d on the carriage and at its other end to the periphery of a wheel M, the periphery of the said wheel being provided with the annular groove art, into which the cord or chain L passes. This wheel M is mounted fast on a shaft journaled in the sleeve m, which latter is mounted in the frame A, as shown. Mounted fast on the same shaft with the wheel M is a disk N, which carries the three small gear-wheels n, n, and n (See Figs. 3 and 11.) Just behind the gear-wheels n, 'n, and n is a disk N, which is loosely mounted on the shaft m and provided with teeth around its periphery, as shown. Secured to the face of this disk N is an interiorly-toothed ring 7?, the teeth of which mesh with the gear-wheels n, n, and 11 A central gear-wheel n also meshes with the gears 01, n, and n and is mounted fast on the shaft m This arrangement constitutes what is known in mechanics as gearing having two degrees of freedom, or that property of the gearing which enables the rotary motion of the shaft m? to be transmitted to the wheel M through the gears 01., n, n M, and n while the gear N is held stationary, or through the gears N, n, n, M, and n while the gear 12, is held stationary. In other words, rotary motion may be imparted to the wheel M either by holding the gear N stationary and rotating the gear n or by holding the latter and rotating the gear-N. The planetary arrangement of gears by which this is effected, as herein shown, is but one of many ways of accomplishing the The other end of the shaft m passes through an upright O, secured to the rear portion of the frame of the machine. This upright carries two electromagnets O and an upwardly-extending rocking arm 0,

stationary pawl o and a spring contact-maker Y 0 which latter is adapted to make contact with the contact-screw 0 when the magnets O attract the armature 0 (See Fig. 8.) The contact-screw 0 9 isinsulated from the frame of the machine, the latter being the negative pole of the electric circuit, as will hereinafter more fully appear. The pawl'o prevents any backward motion of the ratchet when the pawl which imparts the positive forward motion is released. P indicates an electromagnet secured to the frame of the machine, as shown,

and provided with a depending swinging armature p, pivoted in the framep. The lower end of this armature p is provided with a lip 10 which is normally held in engagement with the teeth of the wheel or disk N by the spring 1J3, the tension of which is regulated by the adjusting-screw 10 The action of this mechanism for imparting transverse movement to the carriage is as follows: Immediately after a letter has been printed the magnets 0 become energized and attract the armature 0 This causes the rocking arm 0 to move forward, and this in turn causes the pawl o to rotate the ratchet o a certain distance. The

ratchet being fasten the shaft m causes it to rotate to the same extent, and as this shaft carries the central gear-wheel n the latter will transmit its motion through the gearwheels 12, n, and n to the disk N and from thence to the shaft carrying the wheel M.

This wheel M is thus caused to rotate a certain distance, which obviously will cause the carriage to travel a corresponding distance, being connected thereto by the cord or chain L. The distance which the carriage is thus caused to travel is usually that of a space. The step-by-step movement of the carriage may be kept up until it is desired to return it or allow it to travel back in the opposite direct-ion, as when the end of aline is reached. This is partly accomplished by energizing the magnet P, which is caused thereby to attract its armature and withdraw the lip 10? from engagement with the toothed disk N.

not impart a reverse motion to the carriage. It

onlyreleases it. The actual reversemotion is imparted to the carriage by a falling weight. A spring Q is attached to a lug or pin d on the carriage, and to this spring is attached a cord Q, which passes over a roller q andthence around a pulley q, being connected at its other end to the frame of the machine, as at The pulley q carries a weight of any desired form, which is held within an ordinary dash-pot (1 The paper is fed to the machine and new lines of characters formed by imparting rotary motion to the roughened roller (1 through the shaft or rod 0. In order to impart this rotary motion to the said roller and at the same time allow the rod 0 to move longitudinally, which latter takes place as the carriage travels, the rod 0 carries an elongated sleeve C, having a longitudinal slot 0, along the edges of which extend the flanges c, and as the rod C is provided with a lug 0 (see Figs. 1, 2, and 6,) located between the flanges c of the sleeve 0, it is obvious that when rotary motion is imparted to the sleeve it will be transmitted through the lug c to the red, at the same time allowing the rod to travel longitudinally. This rotary motion of the rod 0 or sleeve 0 is a step-by-step motion imparted thereto by rigidly securing one end of the sleeve C to a short shaft or rod 0 and mounting upon this rod a ratchet 0 This ratchet is actuated by a pawl 0, (see Fig. 5,) which is pivoted upon a rocking arm 0 which in turn is pivoted, as at c, to an upright 0 secured to the frame of the machine, as

shown. The rocking arm 0 carries an armature 0 which is located directly in front of the poles of the electromagnet C". When the magnets C are excited, they attract the armature 0 which causes the pawl c to advance the ratchet a predetermined distance, and when the magnet becomes demagnetized the rocking arm falls back to its original position by virtue of its own weight. The pawl c is provided with an upwardly-extending arm c", carrying a pin or lug 0 against which rests the spring 0 which latter holds the pawl in engagement with the ratchet-teeth. An auxiliary fixed pawl 0 is secured to the rocking arm directly beneath the pawl c, and backward motion of the ratchet is prevented by the pawl 0 The rocking arm 0 also carries an upwardly-extending spring contact-maker c, which every time the magnets C are eX- cited makes contact with the insulated contact-screw 0 and completes an electric circuit, hereinafter described. Thus it will be seen that at each time the magnets C are excited the paper will be fed up a certain distance, and this distance is usually that from one line of printed characters to the next.

The printer herein described being designed to operate with my system of multiplex telegraphy is adapted to print a character for each combination of signals received. To this end my present invention embodies a device for combining the local printer-circuits in such a way that electric currents will be allowed to pass to the various electromagnetic parts of the printer at such times as to cause them to properly perform their funtions relative to the printing of a signal. The combination and distribution mechanism for accomplishing the above is mounted on the same shaft G with the type-wheel, and consists, among other parts, of four segmental rings S, S, S and S all insulated from each other with respect to their mounting, but electrically connected, as hereinafter described, and shown in Fig. 12. These segmental rings are rigidly secured to the sleeve 8", which is loosely mounted on the shaft G, and each ring is provided, respectively, With the rollercontact makers s, s, s", and 8 which are mounted in the spring-supports S, secured to an insulating-plate 5 This plate 3 is se-' cured to one end of an arm 3, which is rigidly secured to a sleeve 8 mounted on the shaft Grand held fast thereto by the set-screws .9 At the opposite end of the arm s from the contact makers is acounterbalance weight 3-. The contact-makers s, .9, s and s driven by the shaft G, sweep around the rings S, S, S and S at a constant speed. These segmental rings are held stationary by means of the arm T, which is rigidly secured at one end to the sleeve carrying the rings and held at its other end against an upright U by thumb-screw t, which is adapted to pass through a slot t in the head if of the said arm. By means of this arrangement of the arm T the angular position of the said rings may be adjusted at will. The construction and electrical connections of this combination and distribution device, as well as its operation, will be more particulary described hereinafter with reference to Figs. 12 and 13.

R, R, R and R represent four polarized relays, which I will designate distributingrelays, the ofiice of which is to close certain circuits by which the various electrical devices of the printer are operated. These relays are mounted upon a common base V, which is secured to the frame of the printer, and have their tongues magnetized by a common magnet.

A represents a plate secured to the frame of the machine, which while forming no essential part of the machine may be used to support resistance-coils on and for other purposes.

In order to describe the complete operation of the printer, which includes the methodof combining the electric circuits and the distribution of the electric current, and also in order to understand the electrical connections of the various parts, reference will be had particularly to Figs. 12 and 13.

R to R represent local selecting-relays, the two R and B being mounted upon a separate base from the others. These relays are substantially similar to the selecting-relays shown and described in my patent application Serial No. 646,017, before referred to, and need not be particularly herein described. The device that I employ for combining the printer-circuits is based upon the general principle of combinations shown and described in my application last above referred tothat is to say, I employ in addition to others nine selecting-relays, which XIO are connected to the same number of groups of segments carried by the rings S and S; but in addition to these nine relays I employ a tenth relay, which is connected to the segments of the ring S Thus it will be seen that in the printing of a signal according to my present invention three selecting-relays operate instead of two, as formerly, though, as will hereinafter appear, it does not necessarily require that three of the said relays be acted upon by the signaling-current for all signals.

The ring S is composed of a plurality of insulated segments 1 1 1 1 1 1 1 and a blankv ally connected, respectively, to those indi-' cated by the same letters on the ring S, only a few of the segments of the separate rings being shown connected, as this is believed to be a sufficient number to illustrate the principle of the idea without rendering the drawing difficult to understand by reason of a m ultiplicity of connections. Each set of the nine segments 1 1 1 1 1 1 1 1 P is connected, respectively, to one contact of each of the relays R ,R ,R R R R R3, R and R that is to say, the segments 1 are connected to the contact r of relay R segments 1 to the contact1 ofrelay R segments 1 to contact r of relay R and so on.

The ring S is composed of four segments-- one segment 1", two segments 1 electrically connected, and a.v blank segment 1corresponding to the'blank segments similarly located in the rings S and S. 'The segment 1 is connected to one contact 7" of the relay R of the same relay, as shown, while the segment 1 is connected to the other contact 1 of relayR. The next ring S contains eight segmentsfour segments 1, electrically connected to the magnet-coil 1 0f the relay R,

the segment 2, electrically connected to the' rings S, S, S and S and the position that they occupy relative to the characters on the type-wheel is most clearly shown by the diagram Fig. 13. From this'diagram it will be seen that for each character on the typewheel there is a corresponding combination between the said segmentsthat is to say, the letter The ring S is also com X,forck'ample,can beprinted only whenthe brushes 5, 3, s and 8 which move together, are all passing over the segments 1 1, 1 and 1, the letter Z when they are passing over segments 1, l l and l, the letter R when they are passing together over 1 1 1 and 1, the numeral 4 when they are passing together over the segments 1, 1 1, and 1, and the comma,for exam ple,when the brushes are passing together over the segments l 1 l and 1, and so on. The three blank spaces indicated Sp, Li, and Bk on the type-wheel correspond to the" combinations of the segments of the rings S, S, S and S that'operate the spacer, liner, and back magnets, respectively. The nine segments 1, 1", 1, 1, 1 1 1", 1 and 1 are combined among themselves in thirty eight combinations, while with the segments of the rings S and S theyform forty-one combinations, beinga suflicient number to print all the letters of the alphabet, numerals, punctuation-marks, and to operate the liner, spacer, and back magnets, as' hereinafter described. It will be seen that the segments land 1 combine with two segments of the rings S and S to print most of the letters, the segments 2,1 and two segments of the rings S and S combine to operate the spacer-magnet, the segments 3, 1 and two segments of the rings S S operate the liner, the segments 1, 1", and two segments of the rings S and S to print numerals, punctuation-marks, and a letter or two,

if desired, and the segments 4, l and two segments of the rings S and S to operate the carriage-reversing or back mechanism. The arrangement and grouping of these segments may be varied if other combinations are found to be better without departing from the spirit of my invention. At the instant that the electric circuits are completed between the respective combinations of segments above described by the reception of telegraphic sig nals the platen will be caused to strike the paper in frontof the character on the typewheel which at that instant corresponds to the combination of circuits established.

Referring again to Fig. 12, X, Y, and Z represent three binding-posts, through which the local electric current that operates the machine enters. The current for actuating the liner-magnet C the printer-magnet k spacer-magnet O, and back magnet P enters through binding-post Z, while that which actuates the relays R, R, R and R enters through posts X and Y. The negative terminal of these electric circuits is the metal frame of the machine.

The operation of the printer is as follows: For each telegraphic signal that is received upon the selecting-relays R to R two relays of the group R R, R, R R R R R and R which are non-adjacent with'respect to the order in which they are acted upon by the receiving-current, will not, closing the electric circuit from the set of segments of the rings S S, to which their contacts are connected. The relay R is also attracted by the signaling-current, so that at the reception of each signal its tongue is either against the contact 1' or contact 1''. It will be assumed, for example, that the signal received acts upon relays R R and R In this event the relay R will close the contact at 0 the relay R the contact at 1', and the relay R will close either the contact 0' or 0" we will assume r At a certain instant the brushes 3 and s will be in contact, respectively, with the segments 1 and 1, which are connected to the contacts 0' and r of the selecting-relays. The brush .9 will rest upon the segment 1 and the brush 8 upon the segment 1. This operation completes an electric circuit, which, beginning at Y, may be traced as follows: The current entering at X passes through coil 1 of relay B into segment 1 of ring S then into brush s and thence into brush 3', segment 1, relay-contact 7", the tongue of relay R then through the frame of the selecting-relays to the tongue of relay R thence into contact 0" and from there to segment 1 of ring S, thence into brush 3, and from there to brush 3 into segment 1 of ring S and thence to contact 0' of relay R and through the tongue of that relay into the frame of the machine, which is the negative terminal of the circuit. When the circuit is thus so established as to allow the current to flow through the magnet-coil 1" of the relay R, its tongue will make contact with the contact 1". This, it will be seen, completes a circuit 5 from the pole Z, through the printer-magnet it the tongue of the relay R, and back to the negative terminal, to which the said relay-tongue is connected. The completion of this circuit-,which includes the proper resistance, will cause the printer-magnet L to attract its armature and cause the platen K to strike the paper and print the character corresponding to the signal transmitted. At the same time that the magnet k attracts it armature and causes a character to be printed the contact-spring 7c is brought against the contact or stop which completes the circuit 6, which so divides, as shown, that a current flows from the terminal X through a proper amount of resistance through the relay magnet-coil 2 returning the tongue of the relay R to its back-stop, which breaks the circuit through the printermagnet and allows the platen to return to its initial position. The current in circuit 6 passes also through the relay-coil 4, bringing the tongue of the relay R against the backstop, and through the coil 6" of relay R bringing its tongue in contact with the stop 1*. Vhen the tongue of relay R makes contact with stop r circuit 8 is completed through the magnet O, which attracts its armature and causes the paper to advance and space automatically after the letter is printed. When the spacer-magnet thus attracts its armature, it causes the spring 0 to engage the contact 0 which completes the circuit 9. This circuit traversing the coil 5 of the relay R causes that relay tongueto be drawn against its back-stop, which breaks the circuit 9 through the spacer-magnet O. The foregoing is what takes place upon the printing of each signal, assuming that the end of a line has not been reached and thatitis not yet desired to reverse theinotion of the carriage. WVhile it was shown in the above explanation how the automatic spacing after the printing of each letter took place, this spacing need not necessarily be automatic, as it may be accomplished at any desired time by the reception of a signal from over the line to space. This is done by sending a signal that will complete the circuit 7, connected to the space-segment 2 of the ring S such signal causing the tongues of the relays R and R for example, to make contact with stops 0' and T The circuit 7 passes from the terminal X through the magnet-coil 6' of the relay R and thence to the segment 2, which at a certain time isboneath the brush 3 into which the current flows. From the brush 5 the current passes to the brush 3', to the segment 1 of ring S, and thence through two of the relays of the group R to R --viz., R and R having their contacts connected to the segments 1 and 1 of the rings S and S by virtue of the signal to space which has been sent over the line. The current passes then from a segment 1 of ring S through the brush 8 to brush s and thence through segment 1 and relay-contact r to the frame of the relay R. The completion of this circuit through the magnet-coil 6 of the relay R causes that relay to close the contact at r, and thus to complete the circuit 8, which will be seen to include the coil of the spacer-magnet O. The

completion of this circuit will cause the magnet 0 to attract the rocking arm 0, which will cause the printer-carriage to move up a space. At the same time the contact-spring 0 engages the contact 0 and completes a circuit 9, which will be seen to traverse the coil 5 of the relay R Obviously the relay R will then break the contact at 7, which will break the circuit 8 through the spacer-magnet, when the rocking arm will return to it's original position. If it is desired to form a new line, the operator at the transmittingstation seudsa line-signal. Assuming that this signal operates the relays R R and R, a circuit 10 will be established through the magnet-coil 8 when the brushes 3,8, 8 and 8 rest, respectively, upon the segments 1, l 1 and 3. This will cause the tongue of the relay R to make contact with the contact T and thus complete the circuit through the liner-magnet C which will causeit to attract its rocking arm 0 and advance the paper the distance of one line, as described. At the same time that the arm 0 is thus attracted it completes the contact at 0 which will establish a circuit 11 through the magnet-coil 7 which causes the relay R to break the contact at r and denergize the spacermagnet 0 The operation of bringing the carriage back to the commencement of a new line or reversingits motion may be accomplished either by the operator at the transmitting-station or itmaybe accomplishedautomatically. Theoperation when accomplished by a signal sent by the transmitter is as follows: Assuming that the signal selected for this purpose is that one which operates selecting-relays RfiRZand R the contacts r and r of relays IR and R are connected,respectively,to the segments 1 and 1 of the rings S and S',and the brushes .9 and 8 come in contact with segments 1 and 1 at the same time that the brushes 3 and 3 come in contact, respectively, with the segments 1 and 4. This will complete an electric circuit in which the current begins from the terminal X, traverses the coil 3 of the relay R, the segments 1 U, and U, and 4, the brushes 5, s, 8 and the tongues of the relays R and R and back through contact r of relay R to the negative frame. When the circuit is thus completed through the magnet-coil 3, the relay R closes the contact at r, and this completes the circuit 12 through the magnet P, which causes that magnet to attract its armature p and release the toothed wheel N,

which, as hereinbefore described, allows the printer-carriage to return to the beginning of a new line. The automatic return of the carriage, as well as the automatic spacing up thereof at each return, is accomplished as follows: The return relay-magnet coil 3 besides being connected to the back segment 4 is also connected to a contact-stud 2, and the magnet-coil 6 is connected to a contact-strip 4;, mounted on a binding-post with and insulated from'a second strip 3. At each advance in the travel of the printer-carriage the arm M rotates a corresponding distance,being aflixed to the sleeve of the wheel m, (see Fig. 4,) so that when the carriage reaches the end of its travel, which is usually the end of a line, the arm M will make contact with the strip 2, which will complete the circuit 13 through the magnet-coil 3 of the relay R, which completes the circuit 12 through the back magnet P and causes it to release the wheelN, as described. When the wheel N is thus released, together with the arm M, it will rotate in a reverse direction, owing to the backward travel of the carriage, and by the time the carriage has traveled its full extent the arm M strikes the contact-strip 3,connected to the negative terminal of the circuit, and brings it into contact with the strip 4E, which is connected to the circuit 1a of the spacer-actuating relay-magnet coil 6 This completes the circuit through the magnet O, which causes the carriage to move forward the distance of a space at each time that it is returned after the completion of a line. M represents a spring to reduce the shock caused by the arm M striking the lug 2'. If by the reception of a signal the relay It is not affected, its tongue will remain against the contact 1", in which event only those characters corresponding to the combination of segments covered by the segment 1 will be printed. The relays R and B may be used for any desired purpose, such as ringing bells, &c.

Instead of using both contacts of the relay R the contact 0' only may be used, in which case the segment Z would be dispensed with.

It will be seen from the foregoing description that the circuit-combining device comprises two partsa circuit-combining part embracing the rings S, S, and S and a current-distributing part consisting of the ring S that is to say, the circuits are combined in the first-named rings, and the current is distributed to the distributing-relays by the ring S The ring 8 in other words, determines to which of the distributing-relays the current in the circuits combined by the other rings shall'pass.

Instead of imparting forward motion to the carriage by a falling weight attached to the pulley q, as described, and returning it to the beginning of a new line by the magnetic and gear mechanisms shown and described I may employ the means for accomplishingthese results as shown in Figs. 14, 15, and 16. In this instance the pulley q is replaced by a pulley The cord or chain L is secured to the carriage, as at (1, passes around the pulley q, then passes once and a half around the pulley M and is then connected to the carriage, as at 61 a spring Q being inserted in its length, as shown. The pulley orwheel M is mounted loosely upon the shaft m and is provided upon one face with the annular flange m in which are cut the gear-teeth m. A spiral spring m is secured at its inner end to the boss of the Wheel M and at its outer end to a fixed pin m on the frame of the machine.- The spring m is held in place by a disk m Lateral movement of the wheel M is prevented by the collars m and m ,between which the boss of the wheel is mounted. Loosely mounted on the shaft m on the other side of the collar m from the wheel M is a soft-iron collar m having at one end an annular flange m, to which is secured a three-arm spider m. At one end of each of the arms of this spider is formed a lug M provided with gear-teeth m, which are adapted to mesh with the teeth m of the Wheel. A soft-iron collar m having at. one end an annular flange m is keyed to the shaft and is hollowed out at its inner end, as at m, to receive the conical end m of the sleeve m A bobbin wound with the wires m fits fast over the sleeve on and extends over the sleeve m the latter being adapted to form a sliding core for the bobbin. A soft-iron shell or sleeve m is screw-threaded upon the flange m and incloses the bobbin, as shown. The current is transmitted to the bobbin through the collector-rings m Three lugs m are secured fast to the sleeve m and ICC each is provided with an arm or rod m each of which rods passes through an aperture in a corresponding arm of the spider m A coilspring m carried upon each of the rods m keeps the teeth of the spider-arms normally in engagement with the teeth m of the wheel. \Vhen the characters are being printed, the carriage is moved forward step by step by the ratchet-and-pawl device herein shown and described or by any other similar suitable device. When this is taking place, the teeth on the spider-arms will be held under the tension of the springs 072 in engagement with the teeth of the wheel M which will cause the wheel to wind up the spring 771 \Vhen, however, it is desired to start the carriage back in the opposite direction, the circuit is com pleted through the coil on, which will suck the core m into the bobbin and disengage the teeth of the spider and wheel. hen this takes place, the wheel, acting under the infiuence of the spring m will start revolving in the opposite direction, carrying the carriage in the same direction. The circuit through the coil m may be made at will or antomatically when the end of a line is reached, all substantially as described for the form of carriage-returning mechanism hereinbefore described.
